28 The network diagram shows the tracks

connecting 8 picnic sites in a nature park. The vertices A to H represents

the picnic sites. The weights on the

edges represent the distances along

the tracks between the picnic sites, in

kilometres. (a) Each picnic site needs to provide

Solution

drinking water. The main water source is at site A. By drawing a minimum

spanning tree in the space below, calculate the minimum length of water pipes

required to supply water to all the sites if the water pipes can only be laid along the tracks.

(b) One day the track between C and H is closed. State the vertices that identify

the shortest path from C to E that avoids the closed track.
